Hello everyone.
I have a problem with my laptop - Satellite L755-S5255, which is less than one year old.
The display sometimes randomly shuts off and there is no other way to revive the computer except for turning it off and then on again. I should mention that the whole computer becomes dead. When I watch a movie and the display shuts off, the movie stops playing and all I can hear "bzzzzzzzzzzzzzzzzzzzzzzzzz" (or something similar). After I restart it, sometimes I get pink dots all over the screen, which won't disappear until the next restart. After the problem appears and I turn the laptop off, I often have to restart it several times to resume working on it - the display shuts off again and again before the "Log In" screen. After 3 or 4 restarts everything is OK again. It boots fine into safe mode.
I have tried reinstalling videocard drivers (clean install from safe mode), and an upgrade from Windows 7 Home Premium to Ultimate also didn't help (not that I was trying to fix the problem with that, I just got a chance to install it). I thought that this is just a hardcore version of the BSOD, but no, the Event Viewer doesn't show anything (except for "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.)
I don't know if the problem is in hardware or software. Would please help me to solve it? Thank you.
